Research summary

Contributions are concentrated in templated synthesis of ordered mesoporous materials and their use in catalysis, separation, and energy storage. Triblock copolymer templating in acidic media yielded SBA-15, a hexagonal mesoporous silica (space group p6mm) with uniform pore sizes from 46 to 300 Angstroms, interlattice d spacings up to 320 Angstroms, pore volume fractions up to 0.85, and silica wall thicknesses of 31-64 Angstroms after calcination at 500 C [1]. Use of nonionic alkyl PEO oligomeric surfactants and poly(alkylene oxide) block copolymers in acid media produced a family of highly ordered mesoporous silicas (20-300 Angstroms) with cubic Im-3m, Pm-3m, 3-d hexagonal P6_3/mmc, 2-d hexagonal p6mm, and lamellar L_alpha symmetries [2]. Morphological control of SBA-15 was further developed [7], and block-copolymer templating was extended to ordered mesoporous TiO2, ZrO2, Nb2O5, Ta2O5, Al2O3, SnO2, WO3, HfO2, and mixed oxides up to 14-nm pores, using inorganic salts rather than alkoxides as precursors to form thermally stable semicrystalline frameworks [8]. Soft-templating approaches to mesoporous silicates were comprehensively reviewed in Chemical Reviews [4], and direct transformation of phenol-formaldehyde resins around triblock-copolymer templates yielded ordered mesoporous polymers and hexagonal/cubic carbon mesostructures with stability above 1400 C [6]. Superparamagnetic Fe3O4@SiO2 microspheres with perpendicularly aligned mesoporous silica shells (53.3 emu/g magnetization, 365 m^2/g surface area, 2.3 nm pores) achieved >95% microcystin removal under magnetic separation [5]. A review of carbon materials for chemical capacitive energy storage compared activated carbons, carbon nanotubes, and template-synthesized porous carbons as supercapacitor electrodes [3]. The methodological signature is amphiphilic self-assembly of block-copolymer micelles co-organized with inorganic precursors, followed by template removal to produce predesigned pore architectures.
